"When a car or automaker receives bad press, people sense an opportunity to pick up a bargain," noted Edmunds.com CEO Jeremy Anwyl. "We saw the same reaction from consumers when Chrysler and General Motors declared bankruptcy last year."

These shoppers may not actually want to buy a car with a potentially hazardous defect, of course. Shortly after the problem came to light, Toyota revealed that it had instituted a "running fix" on the Prius production line in Japan, so cars produced beginning some time in January don't have the problem.

Besides that, shoppers may be putting their faith in an eventual recall, too, said Edmunds.com spokeswoman Jeannine Fallon.

"There's still trust the automaker will have it taken care of if there is a problem," she said.

In the week leading up to the first news reports of an apparent problem, about 7.4% of those researching compact cars were considering a Prius. As of Thursday, after the news broke, 8.7% did.

It was revealed late Tuesday that Prius owners had lodged more than 100 complaints of a problem in which the car's brakes briefly hesitated to work on bumpy or potholed roads. As of Wednesday, four crashes had been alleged as a result of the problem.
